Polymers are either natural or synthetic macromolecules composed of many repeating units (monomers) usually arranged in the form of a chain. Examples of polymers are silk, rubber, silicone, DNA and proteins.

    Low-cost, efficient hydrogen production via water electrolysis is expected to be an important part of a future hydrogen economy. Towards this end, new polymers with high stability are demonstrated and paired with low-cost, earth-abundant metal catalysts in alkaline membrane electrolyzers.

    Organic polymers have demonstrated promise as photocatalysts, but their photocatalytic efficiencies remain relatively low. Now, borrowing principles from organic photovoltaics, heterojunctions of polymer photocatalysts and small molecule acceptors have been shown to have excellent solar hydrogen production efficiencies.

    It is crucial to replace fossil fuel-based plastics with biodegradable ones that are made from renewable sources. Now, a new generation of bioplastics has been prepared through the stereoselective polymerization of diastereomeric monomers — a synthetic approach that allows tuning of the materials’ toughness, ductility and melting point.
